IPMI fencing involves the instance interacting with the IPMI device and
telling it to power-cycle/reset/whatever the target node. It waits for
a confirmation, then tells the cluster SW the fencing operation was
successful. If the instance is running on the same node, it will be
blown away when the node is reset.
